Answer:
240, 1800, 2040
Step-by-step explanation:
First find the surface area of the shape - base = 3 x 15 x 2 + 40 x 15 + 40 x 3 x 2 = 930 m ^2
Now find the area of base = 40 x 15 = 600
Now, the cost of painting = 10 pounds for 25 m^2. SO here cost = 600 / 25 x 10 = 24 x 10 = 240 pounds.
Now cost of tiles = 600 x 3 = 1800
Total cost = 1800 +240 = 2040
